I’m a believer in Foursquare. It’s the most innovative & fun social networking phenom, making waves in the world. I use it for fun & for business (click here to see how). Check me later for info on my Open House!

And today it becomes clear how we’ll be seeing it used from now on. Paraphrasing:

Just shout “Go Steelers” or “Go Packers” on Foursquare during the game to get a badge of the team you support.
Special badges are nothing new, but promoted venues add something more: anybody who picks up one of these three badges gets a promo code for 20% off merchandise on NFL.com. It’s the first Foursquare-wide discount/promotion, but it likely won’t be the last. Now that Foursquare has built the infrastructure to do something like this, it’s possible they could launch regular check-in deals for all users, much like Groupon or Yelp.
